Just stripped down my 4 speed gearbox, the bearing on the output shaft seems to have a coating of copper on it, I presume it’s a 6205 bearing but it measures .002” over size? I’ve tried a 6205 bearing on the casting and it’s a slide fit at best, I presume the copper coating is to pack it out, has anyone had a similar experience? Or does it use a special bearing?

Hi I have brought a tiger cub trials bike as a project I have had it running before I stripe the bike for a frame rebuild. The engine has been in a frame on my bench on refitting it back in the frame I can not get oil too return from the engine when it is running I am sure I have fitted the oil feed pipes correctly any adivce

Some help please guy's. I have just had a British hub co hub c/w with cushdrive assembly restrung with stainless spokes and a new Morad 2.15 alloy rim. All looks lovely with new sprocket and hub powder coated etc etc. However when offered into the James Captain K7 frame and swingarm with the rear drive sprocket aligned to the engine sprocket, the centre of the tyre is about 1" offset to the right of the frame, making the wheel offset to the centre line of the frame. There is an element of adjustment that I have made with spacers etc, but to get the wheel centralised to the centre line of the frame means that the chain is misaligned to the engine drive sprocket. I was …

Hi all, i have a friend who is without internet access, and is currently building a Bantam, he now has a rolling chassis, and the next stage of the build will the motor, without having to take a second mortgauge out what would be the best mods he could do to the motor. ( 187 cc big bore ) And are there any web sites where i can print info off for him. Many thanks HIGGO.

Do not know if this has been on here before but if so I did not see it, Is it any disadvbantage to run a tubeless type rear tyre with a tube in on a conventional rim as tube type rear tyres are not stocked by many dealers.

I use Pirelli MT43 tyres on my B40 which unlike a lot of trials tyres are ok for road use. I once tried a Michelin trials competition and after a couple of miles it heated up and the bike was un rideable. I want a tyre for my Norton but as it has a 19” wheel tyre choice is limited. Pirelli don’t do an MT43 and the only others I can find are an Ensign which isn’t really a proper trials tyre and a Mitas. The Mitas looks like a full 400x19 trials tyre but I’m unsure as to whether it will be too soft for the road. The bike will mostly be used on the road but I might do the occasional long distance trial etc. I’m not bothered about wear characteristics or trials grip but …

Hi Guys, Is the Talmag trial still on this sunday at Hungry Hill, Aldershot. Last year it was cancelled, if so its a good day out, especially the sidcars bouncing valves up the climbs!! triton

What is the best gearing set up for more top end on a mountain cub , it would do around 45mph normally but I am not going off road and would like to see maybe an extra 10mph......would fitting a normal tiger cub gearbox internals from a road going fit in and give me what I want ? Thanks in advance

I’ve just acquired a bantam D7 bottom end (everything accept a barrel piston & head) I would like to fit a D14 top end, I presume it’s a straight fit. But did the D14 have any difference to the crankshaft, crankcase volume or transfer port alignment? Basically what I want to know is, will I get the same power output as a D14?

I am preparing a1955 James in trials trim for this years Beamish Trophy Trial. I want to improve the robustness of the ignition system by doing away with the villiers ignition coil and using an external coil. I have just ordered a FS1E 6 volt AC coil. I need to know in very simple easy steps how to modify the current villiers system sso that I can use the new coil. A wiring diagram would be a great help. I have read the page in the Villiers improvement handbook but it has confused me [not difficult as elctrics are not my strong point.] I really need some expert help but in very simple terms. Can anyone help. I will watch to see what help is given and I can also be contact…

Has anyone found an "off the shelf" front brake cable suitable for Bantam/Cub front hub, maybe off another t. shock bike?? Thanks in advance.......

Does anyone know if Norton Villiers are still going, I’ve sent a couple of emails with no reply? I keep meaning to ring but its not always easy when I’m working!

Hey I'm building a c15/b40 trials bike and I've just picked up some mz forks 35mm however there is no bushes??? The stantion seem to wobble a bit in the seals just wondered if these forks were supposed to have bushes or if this is normal? Cheers luke

Could someone help with an answer to my silly question?. I have just purchased a set of the new type of tube gaskets, the set comes with a large black rubber seal which I assume goes in the bottom and two composite type gaskets of different thicknesses . The black one was a right pain to get in as it seemed too thick but I eventually got it in with the aid of some silicon lube, Now for the silly question; what do you do with the TWO composite gaskets?? I would rather ask the question and get advice before putting it together and it leaking. (My cub has a square barrel and head) any advice gladly received

Have a mate that has fallen in love with Triumph Twins, does anyone know who and where the Hardy Triumphs come/came from? Are they still about?

For anyone with a pre 60 registered or manufactured bike/vehicle. I tried to tax my AJS today and the computer said no - Mot not on record,it runs out on the 20th of Feb.(One side of the form says Mot required,the other side says from the 20th of Nov 2012 its not needed) The new tax disc is from the 1st of march.Tried local post office and online,the helpful lady gave me a number to call.Some time and many options later I got hold of the chap that actually knows - you need a form V112 available here; http://www.direct.gov.uk/prod_consum_dg/groups/dg_digitalassets/@dg/@en/@motor/documents/digitalasset/dg_065277.pdf This will allow the post office to let you get your free…

I See some billet yokes for the cub have a 1.5° offset between the fork tubes and spindle, which way does this offset go? (Front wheel towards the down tube, or further away) And what’s the reason, to tighten up the steering angle or to help the front wheel clear the frame?

What modern ignition do people prefer for a Triumph twin 350, PVL or Electrex world?

Hello I have a nice rear wheel built on a D10 half width hub that I used to run in a C15 frame and swinging arm. I was thinking about using it in a B40 WD frame and swinging arm I have for a vintage Mx build. The spindle is obviously a little short in the B40 WD swinging arm, are there any other longer spindles that fit the Bantam hub to help with this?
